Abstract: The application provides an optical network apparatus and an optical module. The optical network apparatus is configured to: convert, by a processing chip, the received N electrical signals from a board interface chip into a first electrical signal and a second electrical signal; and send the above two electrical signals to a first optical transmission component and a second optical transmission component, respectively; convert, by the first optical transmission component, the first electrical signal into a first optical signal; and convert, by the second optical transmission component, the second electrical signal into a second optical signal. The N to-be-sent electrical signals are combined, and only two optical transmission components are connected to the processing chip. Therefore, the processing chip does not need to be connected to four optical transmission components, fewer optical transmission components are required, and costs are reduced.

Abstract: A method for detecting an MPI noise problem. The method includes: receiving a first signal, where the first signal includes a service signal sent by a sending device and an MPI noise signal generated by an MPI noise generator, and the MPI noise generator is disposed between the sending device and a receiving device of the service signal; determining whether a packet loss occurs in the service signal; and when a packet loss occurs in the service signal, determining that there is an MPI noise problem in an optical fiber link between the sending device and the receiving device. Therefore, when a packet loss occurs in a service signal that passes through an optical fiber link between a transmit end and a receive end, it can be determined that there is an MPI noise problem in the optical fiber link.
